CAN-SPOUT.

To all whom it may concern: 4

Be it known that I, SIDNEY WHITE, a subject of the King of Great Britain, and resident of San Francisco, in the county of San Francisco and State of California, have invented a certain new and useful Improvement in Can-spouts, of which the followmg is a specification.

My invention relates to spouts and par-.

ticularly to a form of spout that may be readily positioned in and removed from a can or other container.

Many forms of liquid, of which milk offers an excellent example, are put up in air-tight tin cans and extracted for use simply by perforating the can and pourmg the contents out through the orifice formed. This is an unsatisfactory and unsanitary method of removingthe contents because of its appearance if the can itself is placed upon the table, because of the necessity of procuring an instrument for puncturing the can each time one is opened, and because the liquid flows in contact with the exterior of the can itself. Other forms of liquid, such as illuminating oils, lubricating oils, and syrups, are frequently sold in containers havmg spouts attached thereto, thereby adding considerably to their cost. Furthermore these spouts frequently become ruptured 1n handling and transporting and are then a source of annoyance when used.

It is therefore the object of my inventlon to provide a spout for use with the various types of containers illustrated by the above mentioned examples, which can be quickly, easily and firmly fixed in any deslred portion of the container; which provides as an integral part thereof, a means for quickly preparing the container for the 1nsert1on of the spout; which may be provided w th means for preventing leaking at the point of insertion of said spout; and which will be cheap, durable and efficient.

"With these and other objects 1n view, my invention consists of the novel and useful provision, formation, construction, combination and relative arrangement of parts, members and features, all as hereinafter described shown in the drawings, and finally pointe out in the claim.

Similar characters of reference refer to similar parts throughout the several views.

In the drawings,--

tion in position for puncturing the container.

Fig. 2 is a vertical, cross-sectional view of my invention in operative position in acoutamer.

Fig. 3 is a detail vertical cross-section of a portion of my invention showing the threadedportion and flange.

Referring now more particularly to the drawing, 1 indicates a portion of a container. At 2 is indicated the body of the spout having a passage 3 formed therein, a lip 4 formed upon its discharge end, and a flange 5 formed upon the opposite end. Flange 5 is preferably cupped upon its lower surface, as at 6, the portion of the body 2 projecting behaw said flange being threaded as shown at 7, and said threads 7 preferably having their upper surfaces comparatively flat as indicated at 8 and their lower surfaces full or rounded as indicated at 9. At 10 is shown a rubber washer fitted under flange 5, and at 11 is shown a sharply pointed cone shaped spike preferably formed as an integral part of body 2.

When this device is used the body 2 first serves as a handle by means of which the point of spike 11 is forced through the wall of the container 1 at the desired place. The base of spike 11 is made of approximately the same size as the end of the threaded portion 7 of body 2, therefore when spike 11 has been forced clear through the metal it is withdrawn and the threaded end 7 of body 2 inserted in the resulting orifice. In forming the orifice in this way no metal is removed but the round surface of the spike splits it up and forces it inwardly. When the spike is removed the metal forming the edge of the orifice is found to be broken and jagged, the portions forced inwardly curling up into small rolls.

As the threaded end 7 of body 2 is screwed into the orifice the flattened upper side of the large thread engages the small rolls and the jagged edge above referred to and draws flange 5 down tightly against container 1, the washer 10 being positioned between the two members forms a tight joint. The rounded or full lower side of the thread 7 helps to secure a firmer grip upon the ragged edge of the metal than if the thread is simply V shaped in cross-section as usually made. The coarse thread as formed on threaded portion 7 secures such a grip on the broken edge of'the inetal that it will, if i ur ed. wi h ufiic e f rce, ra h met l up into the cupped formation under flange 5 as clearly shown at 12' 5 Having thus described my invention, What I claim as new and desire to secure by Letters Patent, is

10 tilated edge of a can opening, said thread having a substantially flat upper surface perpendicular to the axis of said threaded end, an edged perimeter and a convex lower surface, and oi substantially uniform depth throughout its length, and an annular flange having a coneavesurface dlreeted toward 7 said threaded end and positioned ad acent said threaded end, and adapted to en 'age said can a distance from said mutilated edge.

In testimony- Whereof I have hereunto affixed my signature this 21st day of February, 1917.
